Description of Issue

No longer able to connect iPhone Roon app to a ROON Core.

Here’s a series of screenshots in sequence:


It goes through a series of connecting & connection failed, then finally never finding the Core again.

The applications were close and restated on both the PC’s and the iPhone.

On the same network Roon running on one macBook is able to control Roon Core on the other.

Appreciate any thoughts!

Fixed it!

Needed to change security settings on the iPhone in Roon section to allow access to local networks.
